Colored flame candle

ABSTRACT

A candle which burns with a colored flame. The candle has an inner body of solid combustible material, through which extends a wick. The inner body is coated with a higher melting temperature combustible material. Into the outer coating is incorporated a material, which, when exposed to the heat of the flame, yields a flame of a desired color.

United States Patent F/ 3. 1 1 z 2 a 4/27 7) 22 i I'WICK COLORED FLAMECANDLE This invention relates to a candle which burns with a bright andclear color in the flame, the color depending upon the material used inits production. We do not claim that the nature of the color-producingmaterial is new; in fact it can be one of many of the same metallicand/or nonmetallic compounds which have been described in previouspatents on candles which burn with various colored flames. What we claimto be new, and the reason for the distinctly superior performance ofthis candle over any previously described, is the position of thecolor-producing material in the candle.

FIG. I is a vertical section of the candle.

FIG. 2 is a vertical section of the candle showing the outer coatingheld in the flame area.

Candles described previously have had the color-producing materialincorporated by various means into either the wick or into the body ofthe candle. We have found that the flame color generated under theseconditions is weak and pale. The

' problem is that the temperature to which the chromogenic material isexposed is too low to produce a satisfactory color. However, thetemperature at the bottom outer boundary of the flame is greater thanthe temperature at points along the wick or where the body of the candleis molten. Chromogenic agents are capable of producing truly brilliantcolors only at the higher temperatures which exist above the body of anormal candleon the boundary of the flame. In our invention, thecolor-producing material is placed in an optimal position in the flamein the following way: a candle is produced by any of the modes ofmanufacture utilizing any of the materials of candle production, theneither sprayed with or dipped into a resin, plastic or other material(FIG. I) which has a melting point such that the outer surface of thecandle remains near a very hot portion of the flame forming a deep cup,the rim of which is on the boundary of the flame (FIG. 2).Alternatively, the color-producing material may be incorporated into theouter coat resin, plastic or other material and the two processesaccomplished in one step. In this way the colorproducing material israised to a far higher temperature than that which obtains at pointsalong the wick or where the body of the candle is molten. Excitation ofthe molecules of the color-producing materials at this highertemperature results in a strong color, superior to that which a lowertemperature can produce.

Materials which may be suitable for use in the outer coating includePolyamide Resin from Emery Industries, Inc., Biwax from AlexanderSaunders and Company, Inc., Thermoplastic Polyamide Resin from GeneralMills, Inc., High Temperature Wax from Kindt-Collins Co., Neolyn andPentalyn from Hercules Inc., Nylon 12 from Olin Mathieson ChemicalCorporation, Amberol from Rohm and Haas Co., and Piccolastic fromPennsylvania Industrial Chemical Corporation, but we intend that thematerials listed above are only examples and that our invention is notto be restricted to only these materials.

Candles of various sizes can be produced which function equally well byvarying the size of the wick, the outer coat and the body of the candle.

We claim:

1. A candle including an inner body of solidified combustible materialand a wick extending therethrough; said inner body of solidified fuelhaving an outer coating of a higher melting point combustible materialthan said inner body of fuel, and said outer coating of material havingincorporated therein a material which produces a flame of a desiredcolor.
